Abstract
There is disclosed a transportable device for non-destructively impeding the motion of a land vehicle travelling along a pathway. First and second telescoping devices located on either side of the pathway support a barrier. When the telescoping supports are compressed, the vehicles pass over the barrier unimpeded. When the telescoping supports are extended, the barrier impedes the motion of a land vehicle. At least one deceleration cable mechanically couples the barrier to a braking system. The braking system applies a continuous deceleration force to the vehicle of typically less than 2 g, bringing the vehicle to a stop without damaging either the vehicle or vehicle occupants.
Claims21
A device for impeding the motion of a vehicle travelling along a pathway, comprising:
- a first telescoping support and a second telescoping support anchored to opposing sides of said pathway and having both a compressed height and an extended height;
- a propulsion system being a rapidly combusting chemical mix that is effective to extend said telescoping supports from said compressed height to said extended height;
- a barrier extending between said telescoping supports at a mean first height that is effective to permit passage of said vehicle when said first and second telescoping supports are at said compressed height and a mean second height effective to impede passage of said vehicle when said first and second telescoping supports are at said extended height;
- a brake system;
- and
- at least one deceleration cable mechanically coupling said barrier to said brake system.
